Duotone Unit V5: test and review

Looking for a versatile wing that can do it all? The Duotone Unit V5 2025 is the latest iteration of the essential benchmark in wingfoiling. Available in three versions (Classic, SLS, and D/Lab), it features the new, lighter Mod3S canopy. The SLS version also incorporates Penta TX material, bringing its performance closer to the D/Lab at a more accessible price.

To give you a complete and objective review, we gathered feedback from three testers: Erwan from Watersports (full debrief of all 3 versions), Kevin Perrin (on-water feedback in Pornichet), and Hadou Brunner (D/Lab vs Classic comparison).

Penta TX and the Mod3S Canopy

Erwan from Watersports provides a full debrief after several months of intensive testing across all three configurations. The big news for the Unit V5 is the introduction of Penta TX on the SLS version. Kiteboarders will recognize this material, which has a proven track record. On this wing, it delivers performance very close to the D/Lab, but at a much more reasonable price.

Another major highlight is the new Mod3S canopy. It offers the same stiffness as the old Mod3 but is significantly lighter. This truly transforms the experience on the water, enhancing both handling and overall performance. You'll also find the classic D/Lab and Penta TX, now well-known in kiteboarding, which ensure reduced weight, increased stiffness, and incredible durability.

Power, Stability, and Design

When it comes to performance, the Unit V5 is truly impressive. Its high base power allows for quick starts, even in light wind. All configurations are very stable and offer optimal control.

Regarding design, the wing is a bit more compact, with a slightly reduced wingspan. The windows have been repositioned to improve visibility. The neutral handle is thicker, which makes freefly control easier.

How to Choose Your Version

Classic Version: If you're looking for excellent value, the Classic is perfect for freeride. It starts at €949.

SLS Version: For those who want a good balance between performance and price, the SLS incorporates Penta TX. Price: starting from €1,169.

D/Lab Version: If you're looking for ultimate performance, the D/Lab is the option for you. Ultra-light with Aluula, it starts at €1,939.

Erwan's Conclusion

The Duotone Unit V5 is a wing that continues to stand out for its performance and design, along with its technical innovations. Whether you're a regular rider or a freestyle enthusiast, there's definitely a version that will meet your needs.

Erwan's highlights: high base power, amazing stability, Penta TX offers an excellent performance/price compromise, and the Mod3S canopy is light and revolutionary.

Weak points: slightly less specialized than some dedicated race wings, and the rear handle is a bit limited in strong wind.

Grip and Ergonomics

During an early afternoon session at the Pornichet shipyard, Kevin Perrin tested the Duotone Unit V5. The Unit's handling with the boom is truly excellent; it's quite intuitive with superb grip, and the pistol grip is a real plus for freefly. The Unit offers good ergonomics and, most importantly, is easy to control.

The front freefly handle is now much stiffer, and the sheath doesn't rotate around the core, which is perfect. The wing is stable with a good balance between front and back arm pressure.

Flight Behavior and Attachment

The Unit V5 pulls more upwards during tacks and transitions, but in return, it pivots very well. The boom attachment is robust, and installation is genuinely simple with an M6 TORX screw. Additionally, the covers provided for the middle attachments are foam with double-sided tape.

Versions and Materials

In this review, Hadou compares the new Duotone Unit V5 wings in both D/Lab and Classic versions. The D/Lab wing features a stronger Aluula construction. This makes it lighter and gives it more stiffness. It's a high-end wing with a higher price point, but it delivers superior performance for demanding riders.

The Classic version is constructed from Dacron. This makes it a more accessible wing, though it is heavier. It still offers excellent characteristics. The SLS version provides a middle ground, with certain improvements derived from the D/Lab.

Sizes, Packaging, and Grip

The Unit V5 is available from 2.0 to 7.0 m², depending on the model. The D/Lab will be more effective in smaller sizes due to the stiffness of the Aluula. In comparison, the Classic is more versatile and forgiving on larger surfaces.

The travel bag is well-designed and compact. The leash is not included and must be purchased separately. Your choice between rigid handles and the boom depends on the comfort you're looking for: the boom offers better control for tricks and precision, while rigid handles are lighter and provide good transmission.

Inflation and Stiffness

One Pump technology ensures quick and efficient inflation. Hadou recommends a higher pressure for the D/Lab to best utilize the Aluula construction. For the Classic version, however, you should reduce the pressure for more comfort and flexibility.

On-Water Test

Extreme conditions: Hadou observes better hold in gusts and excellent stability on the D/Lab. The Classic is more flexible and forgiving, but it requires more effort to keep stable. Both versions remain maneuverable and enjoyable.

Light wind: the D/Lab excels even more thanks to its lightness. The Classic requires a bit more technique to harness its power in these conditions.

Versatility and Hadou's Conclusion

The D/Lab is ideal for freerace and speed, with a more direct response. The Classic is more forgiving and versatile, a wing made for riders seeking comfort and ease. Stability is improved in tacks and jibes thanks to optimized balance.

The Unit V5 stands out with its premium material construction, significant improvements in comfort and stability, excellent handling, and the D/Lab's featherlight weight, which makes steering easier. The Unit V5 2025 remains a benchmark in its category. Your choice between versions will primarily depend on your expectations and budget.

The Duotone Unit V5 2025 confirms its status as a versatile wingfoil benchmark. The introduction of the lighter Mod3S canopy, Penta TX on the SLS, and ergonomic improvements (freefly handle, compact design) make it a significant evolution from the V4. Whether you're looking for unbeatable value (Classic), a smart compromise (SLS), or ultimate performance (D/Lab), there's a Unit V5 for every rider and every budget. Three testers with different profiles unanimously agree: this is the versatile wing of 2025.
